    Bernie Thompson TI
    I moved your thread here to the C5000 forum to hopefully get you in touch with some more C5000 specific experts. As to the question at hand I believe the better part of your answer can be found in section 4.3.6 of the datasheet . It looks like there is a prioritization scheme available with the ILR register...

    DSP_KungFu_Master
    Hello, I modified the LCD example (VC5505_CSL\CCS_v3.3_Examples\lcd\example1\) to work under DSP/BIOS. Then I used a PRD task which updates the display 20-30 times per second with data and this works OK. A problem arises when I have some SWI interrupt(s) enabled, the display freezes and I have to...

  • Forum Post: DMA issue: block transfer seems never to stop / interrupts aren't executed

    Raphael19557
    Hi All, I wrote a small application based on the aic3204 sample by Spectrum. I tried to add DMA functionality, like in the USB_Stick_AudioFilter example from TI. Therefore, I configured DMA0 channel 0 to transfer data to the I2S0 Tx buffer and DMA0 channel 2 to transfer data from the I2S0 Rx buffer...

    DSP_KungFu_Master
    Hello dear colleagues developers, Let me first describe my situation: in my code I have several things going on: 1. There is an infinite while loop located in my main() function... after HW and interrupt initialization, execution enters the loop and remains there where it outputs some data on...

    Hyun Kim
    Hi Shinji, Errata is describing the repeated interrupt occured when the CPU is in idle mode. So customers reports are expected. The workaround is to limit the low pulse duration of external inturrupts. Regards, Hyun

  • Forum Post: Re: Setting up interrupts using DSP/BIOS on a c5502

    TommyG
    Robert, I was able to get your project to build by modifying the function name from HWI_pcmTxIRQ to _ HWI_pcmTxIRQ using the configuration tool. This is the preferred method of managing interrupts with DSP BIOS. Also, DSP BIOS takes care of context switch for you, so you don't need to worry about...

    So I'm working on a new design here at work, and the hardware engineer decided on a C5510 and a Linear Tech LTC1407 serial ADC. Since I've never used a C55xx before, and don't know how its DMA engine compares to the EDMA3 from C6000s, I thought I'd try to use the Data Converter Plugin...

    Ullas R
    Hi Tommy, According to the C5505 document, the UART interrupt is mapped to HWI-6 . To confirm the mapping, I enabled the UART interrupt, and wrote a dummy ISR , which just puts some text onto the Transmitter Holding Register (THR) everytime the handler is called. Apart form this, i am polling on the...

    Hello, My name is Ruan and I'm busy implementing a guitar effects pedal on the ezDSP usb Stick. I'm having trouble programming the interrupt vectors to jump to the isr. How can I set up the vector table? Is there a way to program it in c or do you always have to program it in asm like...

  • Forum Post: Re: Interrupt Question

    TommyG
    Ruan, If you are not using DSP/BIOS, then there is a good example of an interrupt vector table in the CSL examples. Look at the file vectors.asm which is located in the CSL folder: \c55xx_csl\src. The example named: \c55xx_csl\ccs_v4.0_examples\intc\CSL_INTC_Example shows how to setup interrupts using...

  • Forum Post: C5505 USB Peripheral - how do the interrupts work?

    TommyG
    It's not clear from the USB PRG how the interrupts work in the USB peripheral. There appear to be 2 different sets of registers that control interrupts. There are the USB Interrupt Source / Mask regeisters described in Table 13 and sec 3.10 - 3.16. Then there are registers in the USB2.0 Core described...

    Frederico, Details of how the DSP CPU handles interrupts is described in CPU Reference Guide ( http://www-s.ti.com/sc/techlit/spru371 ), Chapter 5. This should give you an overview of the operation of the device. Details on how to setup ISR is described in Compiler User Guide ( http://www-s.ti.com...

    M. Marin, The interrupt mapping for the VC5505 is found in the System User's Guide ( http://www-s.ti.com/sc/techlit/sprufp0a ), Chapter 6. I am not aware of any good examples either. There are some docs under the BIOS install folder that have details on how to implement HWI. Regards.

    I have designed a custom TMS320VC5506 board with preliminary firmware which hopes to enable a continuous DMA transfer from DARAM to EMIF CE0. I believe that I have everything set up correctly using the CSL API, and I seem to get at least 10 block transfers, sometimes as many as 50, but the DMA seems...

  • Forum Post: Re: Interrupting Assembly Function with C Code Interrupt

    mjones
    I have been looking at the generated C code for my interrupt (coded in C). The very first thing that it does, before pushing anything, is set and clear bits in the three status registers. With these bits changed before any context save, it seems that certain code that depends on non-default bit values...

  • Forum Post: Re: Interrupting Assembly Function with C Code Interrupt

    mjones
    As a follow-up, my point is that the assembly code that was interrupted was performing 40-bit arithmetic and the M40 bit would have been cleared on C code interrupt return.
